Configuring the ProCurve Wireless Edge Services zl Module
Management Interfaces
SNMP Communities. SNMP v1/v2c uses communities to control various types of
management access. In order for an SNMP v1/v2c server to access the SNMP agent
running on a device such as the Wireless Edge Services zl Module, the server must
know at least one of the community names configured on the device. Each community
name is assigned an access control: read-only or read-write. The access control
assigned to the community determines the operations that an SNMP server can
complete on the Wireless Edge Services zl Module.
A server that knows a device’s read-only community name can view, but not alter,
settings and other information stored on that device. For example, you might want a
particular SNMP server to only monitor traffic on the device. An SNMP server that
knows a device’s read-write community name can change its configuration in
addition to viewing information about it.
The Wireless Edge Services zl Module uses the following community names:
■ public
■ private
■ trap
By default, the public and trap communities have read-only access, and the private
community has read-write access.
For more information on configuring communities, see “SNMP Communities” on
page 2-109. For more information on setting up traps, see “Enabling SNMP Traps”
on page 2-113.
You can also control management access and traps with SNMP v3, as described in
the next section.
SNMP v3 Users.
The management users for the Wireless Edge Services zl Module
are controlled through SNMP v3.
SNMP v3 allows you to create multiple users with different levels of access. For
example, instead of configuring a community name on an SNMP v3 server, you can
configure it with its own username, password, and management privileges.
In addition, SNMP v3 secures communications between the user and the managed
device, transforming the traffic with an encryption algorithm, an authentication
algorithm, or both.
Default SNMP v3 Users—Manager and Operator.
There are two default users:
■ Manager—The manager has read-write access, which means the manager can
configure settings and view information.
